Agência Espacial Brasileira

The Brazilian Space Agency ( pt, Agência Espacial Brasileira; AEB) is the civilian authority in Brazil responsible for the country's space program. It operates a spaceport at Alcântara, and a rocket launch site at Barreira do Inferno. It is the largest and most prominent space agency in Latin America.

The Brazilian Space Agency is the institutional successor of Brazil's space program, which had been managed by the Brazilian military until its transfer to civilian control on 10 February 1994. It suffered a major setback in 2003, when a rocket explosion killed 21 technicians. Brazil successfully launched its first rocket into space, the VSB-30, on 23 October 2004 from the Alcântara Launch Center; several other successful launches have followed. Brazil was briefly a partner in the International Space Station, and in 2006, AEB astronaut Marcos Pontes became the first Brazilian and the first native Portuguese-speaker to go into space, when he arrived at the ISS for a week. During his trip, Pontes carried out eight experiments selected by the Brazilian Space Agency, including testing flight dynamics of saw blades in zero gravity environments. In June 2021, the AEB signed the Artemis Accords to the joint exploration of the Moon and Mars from 2024 as part of the Artemis program.

History

The then president Jânio Quadros in 1960 established a commission that elaborated a national program for the space exploration. As a result of this work, in August 1961, the Organization Group of the National Commission of Space Activities (Portuguese: ''Grupo de Organização da Comissão Nacional de Atividades Espaciais'') was formed, operating in São José dos Campos, in the state of São Paulo. Its researchers participated in international projects in the areas of astronomy, geodesy, geomagnetism and meteorology.

The GOCNAE was replaced in April 1971 by the Institute for Space Research, currently called the National Institute for Space Research (INPE). Since the creation of the then Technical Center of Aeronautics (CTA), the current Department of Aerospace Science and Technology (DCTA) of the Brazilian Air Force, in 1946, the country has been following the international progress in the aerospace sector.

With the creation of the Technological Institute of Aeronautics (ITA), a fully qualified institution was formed to train highly qualified human resources in areas of state-of-the-art technology. The DCTA, through the ITA and the Institute of Aeronautics and Space (IAE), play a key role in the consolidation of the Brazilian space program.

In the early 1970s, the Brazilian Space Activities Commission (COBAE) was created - a body linked to the then General Staff of the Armed Forces (EMFA) - to coordinate and monitor the implementation of the space program. This coordinating role, in February 1994, was transferred to the Brazilian Space Agency. The creation of the AEB represents a change in government orientation by establishing a central coordinating body for the space program, reporting directly to the Presidency of the Republic.

In 2011 Argentina's defense minister, Arturo Puricelli, made a proposal to the Brazilian minister, Celso Amorim, for the creation of a unified South American space agency by the year 2025, according to the European Space Agency. In 2015, however, the Brazilian Space Agency and the Ministry of Defense rejected the Argentine proposal "because it understood that it would be an organ that would yield a lot of bureaucracy and few results like the 'confederation' proposed by the United States and never came to anything" and also because, according to the agency's adviser, "A regional space agency would reverberate in the Brazilian pocket that, due to its territorial size, would end up getting most of the invoice to pay".

Launch sites

Alcântara Space Center

The Alcântara Launch Center ( pt, Centro de Lançamento de Alcântara; CLA) is the main launch site and operational center of the Brazilian Space Agency.Centros de Lançamentos: CLA
Brazilian Space Agency. Retrieved on 2009-07-30. It is located in the peninsula of Alcântara, in the state of Maranhão.Alcantara Launch Center (2°20'S; 44°24'W)
GlobalSecurity.org. Retrieved on 2009-07-30. This region presents some excellent requirements, such as low population density, excellent security conditions and easiness of aerial and maritime access. The most important factor is its closeness to the Equator - Alcântara is the closest launching base to the Equator. This gives the launch site a significant advantage in launching geosynchronous satellites.

Barreira do Inferno Launch Center

The Barreira do Inferno Launch Center ( pt, Centro de Lançamento da Barreira do Inferno; CLBI) is a rocket launch base of the Brazilian Space Agency. It is located in the city of Parnamirim, in the state of Rio Grande do Norte. It is primarily used to launch sounding rockets and to support the Alcântara Launch Center.

Launch vehicles

Sounding rockets

The Brazilian Space Agency has operated a series of sounding rockets.
* Sonda I
* Sonda II
* Sonda III
* Sonda IV
* VSB-30
* VS-30
* VS-40
* VS-50 (projected, will use the new S-50 rocket engine)

VLM

Brazil has forged a cooperative arrangement with Germany to develop a dedicated micro-satellite launch vehicle. As a result, the VLM "Veiculo Lançador de Microsatelites" (Microsatelite Launch Vehicle) based on the S50 rocket engine is being studied, with the objective of orbiting satellites up to 150 kg in circular orbits ranging from 250 to 700 km. The first qualifying and test flight will be on 2022 from the Alcântara Space Center. The second flight is scheduled for the following years as part of the SHEFEX mission, to be conducted also from Alcântara, in partnership with the German Aerospace Center (DLR).

VLS

The VLS - Satellite Launch Vehicle ( pt, Veículo Lançador de Satélites) was the Brazilian Space Agency's main satellite launch vehicle. It is a four-stage rocket composed of a core and four strap-on motors.VLS (Brazilian rocket)
The Internet Encyclopedia of Science. Retrieved on 2009-07-29. The vehicle's first stage has four solid fuel motors derived from the Sonda sounding rockets. It is intended to deploy 100 to 380 kg satellites into 200 to 1200 km orbit, or to deploy 75 to 275 kg payloads into 200 to 1000 km polar orbit. The first 3 prototypes for the vehicle failed to launch, with the 3rd exploding on the launch pad in 2003 resulting in the deaths of 21 AEB personnel.

The VLS-1 V4 prototype was expected a launch in 2013.''Saiba como está o projeto Veículo Lançador de Satélite (VLS)''
Brazilian Air Force. Retrieved on 2012-03-06. . After subsequent delays, the project was cancelled in 2016.

Southern Cross program

The Brazilian Space Agency was developing a new family of launch vehicles in cooperation with the Russian Federal Space Agency.Russia Begins Elbowing Ukraine Out From Brazil's Space Program
SpaceDaily.com. Retrieved on 2009-07-29. The five rockets of the Southern Cross family will be based on Russia's Angara vehicle and liquid-propellant engines.

The first stage of the VLS Gama, Delta and Epsilon rockets was to be powered by a unit based on the RD-191 engine. The second stage, which will be the same for all the Southern Cross rockets, will be driven by an engine based on the Molniya rocket. The third stage will be a solid-propellant booster based on an upgraded version of the VLS-1. The program was named "Southern Cross" in reference to the Crux constellation, present on the flag of Brazil and composed of five stars.Programa de Veículos Lançadoeres de Satélites Cruzeiro do Sul
Brazilian General Command for Aerospace Technology. Retrieved on 2009-07-29. Hence the names of the future launch vehicles:
*VLS Alfa (light-weight rocket)

The first rocket to be developed. As a direct modification of the VLS-1 of the original project, replacing the fourth and fifth stages by a single liquid fuel engine. It can place payloads in the range 200–400 kg in orbits up to 750 km.
*VLS Beta (light-weight rocket)

Consisting of three stages without auxiliary thrusters. The first stage is a solid fuel propellant 40 tons, the second will have 30 tons of thrust engine and the latter will be 7.5 tons of thrust, with the same mixture "Kerolox". It can place payloads up to 800 kg in orbits up to 800 km.
*VLS Gama (light-weight rocket)

The VLS Gama launcher is part of the light-weight class, but using the near-equatorial position of the Alcântara Launch Center, it can place almost 1 ton of payload into orbit up to 800 km.
*VLS Delta (medium-weight rocket)

The VLS Delta launcher is a medium-weight rocket and differs from the Gamma by having four solid-propellant boosters attached to the first stage. Its payload deliverable to a geostationary orbit is 2 tons.
*VLS Epsilon (heavy-weight rocket)

The VLS Epsilon launcher is a heavy-weight rocket with three identical units attached to the first stage. It can place a 4 tons spacecraft in geostationary orbit, if it is launched from Alcântara.

The Brazilian government was planning to allocate $1 billion dollars for the project over six years. It has already set aside $650 million for the construction of five launch pads able to handle up to 12 launches per year. The program was scheduled to be completed by 2022. However, it was cancelled by Brazilian President Dilma Rouseff. Instead, Brazil will focus on a series of smaller launch vehicles that appear to rely more on home-grown technology.

14-X

Brazil is also investing in the domain of the hypersonic technology. The 14-X, a hypersonic glide vehicle (HGV) under development with the Brazilian Air Force, was conceived in 2007 and launched on 14 February 2022, by a VSB-30 rocket, reaching to 100,000 feet of altitude and a maximum speed of Mach 10.
